Access over the Internet
It is possible to access the Wifi Bridge from virtually all over the world when an
Internet connection is available. So you could turn on your coffee machine from the
office already for example.
For this purpose forward port 80 in the settings of your router to the bridge. The
target IP address has to be the address of the Wifi Bridge shown in Lightman Studio.
For test purposes you can disable Wifi in your smartphone and enter the IP address
you got from the ISP. With a little delay the web interface should show up if a GSM or
UMTS connection is available.
Most DSL lines use dynamic IPs. This means that the IP address will change daily. To
keep access to your web interface anyway you will need a so called DynDns account.
There are certain providers which offer this service free of cost. A well known provider
is
www.no-ip.com
for example. There you get a URL like myhouse.no-ip.com under
which the interface is reachable all time. Another well known provider is
www.dyndns.org
. Unfortunately they started charging a yearly fee, but the service
quality is excellent.
Modification of the web interface
Shortly more detailed information will be presented in our FAQ how to modify the web
interface. Just some basic information at this place.
The template for the creation of the interface is stored in the /html folder of the
Lightman Studio installation. When pressing the start button Lightman Studio loads
the template and generates the customized interface based on the currently loaded
configuration. The result is stored in the /html_temp folder before it is compressed
and uploaded to the Bridge. In contrast to the template the /html_temp folder
contains all light scenes, zones and actuators.
If you want to modify the interface we recommend to create a copy of the /teml_temp
folder after the first upload and store it in a different folder. Now the HTML and CSS
10
files can be altered by the user. Lightman Studio offers the possibility to select a
source folder for the web data. Here you select your newly created folder and from
now on this will be used when uploading data to the Bridge.
Information for developers
In the web space of the bridge there is a file called config.xml. This includes all zones,
light scenes and actuators, together with strings for all commands available for each
actuator and light scene. It is sufficient to send a http-request with this string to the
Bridge in order to execute a command or to trigger a light scene. So you can easily
create your own software resp. app to control the Bridge. More detailed information
can be found shortly in the FAQ section of your homepage.
Firmware-Update
The Wifi Bridge supports firmware updates. It can be expected that more functions
will be added to the Bridge in course of time. For this purpose there is the tab
firmware update in the Wifi Bridge options of Lightman Studio. In most cases the
update can be done over-the-air. In case this process does not work properly, maybe
because UDP traffic is restricted in your network, you can attach the Light-Manager
and the bridge to the PC. Then the log screen will show detailed information during
the update procedure and it should be possible easily to find out where it hangs.
Trouble shooting
If the Wifi Bridge does not connect to a specific network mostly one of the following
reasons are the cause:
1.
The 802.11
b
mode is not activated. Please check the settings of your router.
For test purposes it can be helpful to temporarily set it to pure 802.11 b
mode. Some routers offer an auto mode. This should not be used, especially
in the test phase. We recommend mixed 802.11 b/g or b/g/n mode.
